It's a Daiso eyebrow razor.

This is a Daiso eyebrow trimmer with excellent value for money.

I use it to trim my eyebrows, remove stray hairs on my philtrum, or trim fine facial hairs. The blade is small and sharp, so it seems to be excellent for removing fine hairs.

Also, I sometimes remove my calf hair in the summer. Since it doesn't grow very thick, this single blade is enough to remove it quite cleanly.

Since it comes as a set of three, it offers the best value for money. I am currently using one for eyebrow grooming, one for removing fine facial hair under my philtrum, and another for calf hair removal, and I think there is nothing better than this haha.
